LagFixer - Ultimate Performance Solution v1.5.1.3

Optimize your server performance by up to 200%!
  • Changed Updater which now listens to the Modrinth API instead of spigotmc
  • Removed option others in EntityLimiter, this option caused problems, it blocked the itemframe and the dropping of items
  • Fixed color formatting in the module list menu. (This was a visual issue only and did not affect the plugin’s functionality)
  • Improved subcommand handling for the /lagfixer command.
  • Fixed an issue where the module configuration menu stopped working after making changes.
  • Optimized the module list and configuration menus by removing the function that cleared and rebuilt the inventory each time; unchanged items now remain persistent between updates.
  • Optimized reflection in DeprecatedBukkitSupport for unsupported versions that rely on NMS class adaptation.
  • Added a new "others" limit type in EntityLimiter, which restricts the spawning of entities other than creatures, items, vehicles, and projectiles (e.g. armor stands).
  • Stopped using Google Commons’ ImmutableList to improve compatibility with older Minecraft versions that do not support this library.
  • Fixed an issue in ErrorsManager, which previously failed to report plugin errors properly.
  • Changed the resource channel from Alpha to Release.
  • Added support for Minecraft versions 1.21.4 and 1.21.5.
  • Updated support for LevelledMobs.
  • Renamed CustomAi to MobAiReducer.
  • Renamed CustomVehicle to VehicleMotionReducer.
  • Removed support for versions 1.13–1.16.5 due to required rework. Mapping issues are causing delays, and additional time is needed for proper implementation.
